Where is the leak detection pump on a Chevy Volt?
The leak detection pump on a Chevy Volt is located in the vehicle's fuel system, specifically near the fuel tank. This pump plays a crucial role in detecting any potential fuel leaks, ensuring the safety and proper functioning of the vehicle's fuel system.
Understanding the Leak Detection Pump
The leak detection pump, also known as the evaporative emission (EVAP) system leak detection pump, is a component of the Chevy Volt's fuel system. Its primary function is to continuously monitor the fuel system for any leaks or evaporative emissions, which could pose a safety hazard or negatively impact the vehicle's performance and emissions.
The leak detection pump is responsible for creating a vacuum in the fuel system, allowing it to detect even the smallest of leaks. If a leak is detected, the pump will alert the vehicle's onboard computer, which can then trigger a warning light on the dashboard, alerting the driver to the issue.
Location of the Leak Detection Pump
On the Chevy Volt, the leak detection pump is typically located near the fuel tank, often in the rear of the vehicle. The exact location may vary slightly depending on the specific model year and production year of the Volt, but it is generally found in the vicinity of the fuel tank.
To access the leak detection pump, you may need to remove or partially disassemble certain components, such as the rear trim panels or the fuel tank itself. It is recommended to consult your Chevy Volt's service manual or seek the assistance of a qualified automotive technician when attempting to locate and service the leak detection pump.
Importance of the Leak Detection Pump
The leak detection pump plays a crucial role in the overall safety and performance of the Chevy Volt's fuel system. By continuously monitoring for leaks, the pump helps prevent the buildup of flammable vapors, which could pose a fire hazard. Additionally, the pump's ability to detect even small leaks can help maintain the vehicle's fuel efficiency and emissions compliance.
Regular maintenance and inspection of the leak detection pump, as recommended by the manufacturer, can help ensure the continued reliable operation of the Chevy Volt's fuel system and prevent any potential issues related to fuel leaks or evaporative emissions.

How long does a leak detection take?
The Water Leak Detection Timeframe
It usually takes an hour or less to detect a leak.
How do I fix the code p2400?
The most common repair for this trouble code is to replace a faulty leak detection pump. Next would be to repair a broken or leaking hose leading to or from the leak detection pump. Finally, after those repairs, the next most common fix is to repair the wiring leading to the leak detection pump.
Does a bad water pump leak when engine is off?
Will a Faulty Water Pump Leak When the Engine Is Off? In some vehicles, the water pump will stop leaking once the engine cools down and will start leaking again once the engine reaches its operating temperature. Intermittent leaks are often a sign of water pump wear and seal failure.
What happens when the leak detection pump goes bad?
A faulty fuel leak detection pump will cause the Service Engine Light to illuminate in the instrument cluster and will trigger a fault code on diagnostic scanners. It will also cause your vehicle to fail an emissions test. These are the exact parts used in this repair.
Can a leaking water pump be fixed?
Repairing a water pump typically involves replacing the faulty pump rather than repairing individual components, as water pumps are generally sealed units.
What is the code P2400 on a Chevy Volt?
The powertrain control module (PCM) will log the P2400 code if it notices the pressure drop in the fuel tank, and it will activate the leak detection pump switch. OBD2 systems might purge the EVAP canister while the engine is running, so avoid packing the fuel tank during refueling.
Can you drive with a fuel vapor leak detection pump?
If it is just an EVAP emissions leak then you will be okay driving as long as it is not leaking actual fuel. Typically the issue is the EVAP ESIM that is located on the canister assembly on these and you can definitely drive if that is what they are referring to.
What is the code for leak detection pump?
P2401 and P2402 codes indicate that there's an issue with your evaporative emissions (EVAP) system. The “Leak Detection Pump” is part of the EVAP system, testing for system leaks and blockages to ensure that the system is working as intended.
Is leak detection covered by insurance?
When you have a leak, never make a claim to your insurance until you have an experienced leak detection company identifies the leak and cause. Leak detection is typically covered by your insurance policy, but it all depends on what type of leak you have.
